Similar to mice, voles emit a high-pitched chirp when communicating with others, however, most of their vocal sounds are on a frequency beyond the human hearing capacity. Even while burrowing and rustling while foraging, most of their sounds are far too quiet for humans to hear.
The tracks that voles make aren’t so much actual track prints as they are the tunnels and burrows they create. Their ‘runways’ are most obvious in the spring and into the summer where you will see furrows with a lack of grass and a rise of top soil by two to three inches and an inch or two wide.
Vole poop are usually greenish-colored pellets found near the burrow entrances, are roughly three-sixteenths of an inch long and often include grass clipping or foliage remnants. As they age, the dropping turn from green to brown or gray.
